WebWithout the patch below, only 32 bits are being transferred, thus leaving in place the (high 32-bit) sign extension of -1. When the sim attempts to execute the instruction noted above, it first checks to make sure that the sign extension for the register being transferred is sane. It is not, and therefore quits printing the UNPREDICTABLE message.
